for printing on wrapping-paper; and the .ob-.

ject thereof is to provide an improved device of this class which isdesigned for use inconnection with .a roll of wrapping-paper from whichstrips or sections of paper may be drawn for use in the usual manner, afurther object being to provide a device of the class specified for usein retail shops and similar places where wrapping-paper is usually keptin rolls and by means of which any desired advertisement may be printedon separate strips, sheets, orsections of the paper as they are drawnfrom and detached from the roll.

The invention is fully disclosed in the following specification, ofwhich the accompanying drawings form a part, in which the separate partsof my improvement are designated by suitable reference characters ineach of the views, and in which- Figure 1 is a side view of a part of amain frame and showing -a part of .-a roll of paper mounted therein andshowing also one form of my improved printing device; Fig. 2, asectional plan view of the device as show-n in Fig. 1, the lineofthesection being that designated as 2 .2 in Fig. .1; Fig. 3, .a viewsimilar to Fig. '1, but showing the printing device in transversesection, the section being taken on the :line 3 3 of Fig. ,2; Fig. 4, asection on the line 4 4 of F ig. 2 looking in the direction of the arrowat; Fig. 5, a view similar to Fig. 4, but looking in the oppositedirection and showing only part of the construction shown in Fig. 4-;Fig. 6, a section on the line 6 6 of Fig. 4.; Fig. 7, a view similar toFig. 1, but.

showinga modification for printing in different colors with part .of theconstruction broken away; Fig. 8, a plan viewof .the de vice as shown inFig. 7 with part of the construction brokenaway, and Fig. 9 a section onthe-line9 90f Fig. 7.

In the practiceof any invention, as-shown in Figs. 1 :to 6, inclusive, Iprovide a main frame comprising side members a :and a top membera andsaid frame may be provided "with anydesired form-of base or maybesupported inany preferred manner. At the top portion of the main frameand at the back thereof is mounted a transverse shaft 1)., one end ofwhich is provided with :an arm 19., rig- Eidly connected therewith, andsaid shaft is provided with supports 1), which are sus,

pended from the .top portion of the main frame and the frontportions ofeach of which is segmental in form and provided with aratchet-teeth b,which form segmental ratch- -ets, .and the shaft 6 is alsoprovidedrcentra'lly with a forwardly-directed arm 6 Mounted on the endportions of the shaft -b within the sides-of the main frame is a mainprinting-frame c, comprising-side membersfc :and springs c are coiled onthe end porations of the shaft 1), and one end of said springs issecured to the supports b :and the other end thereof to the side members0 of the main printing-frame, and these springs c serve to tensionallyhold the main printingframe in its highest position, as shown by the:dotted lines'ctin Fig. 1, in which position the 'front movable portionof said main printingframe ,presses on the top a of the mainframe of thedevice.

Mounted transversely of and in the front portion of the main frame is amain printingicylinder d, the ends .of which are provided with Wheels dformed integrally therewith or rigidly connected therewith, and saidprinting-cylinder is provided centrally with .a type-plate (1 .on whichthe type of anydesired advertisement :may :be placed.

Pivoted in the main printingirame c is .an

inking or supplemental printing-frame e,said supplemental printing-framebeing mount-ed on a transverse rod e the ends of which are supported inthe-sides of the main printingframe 0, and said supplemental printinggagement with'the ratchetmembers-bt. Each end member e ofthesupplementalprintingframe e is provided at the bottom thereof with aforwardly-directed arm g, having a ITO transverse head 9 and each ofsaid end members c of the supplemental printing-frame e is provided onthe opposite sides'of the arm 9 with forwardly-directed fingers g andmounted in the supplemental printing-frame is an inking-roller having apad or cushion e and in practice the ink may be applied to said pad orcushion in any desired manner. Each end of the printing-cylinder d isprovided with a cam-hub (1, having a cam projection d at one sidethereof, and these camhubs (Z or the projections (1 thereof operate inpractice on the heads 9 of the arms 9, and each end of theprinting-cylinder d is also provided with a pivoted pawl d, and the endsof said printing-cylinder are also provided with annular raised portions61 having recesses d, in which the pawls d" are pivoted and by means ofwhich the movement of said pawls is limited.

Mounted on theends of the shaft (1" of the prmting-cylinder and rigidlysecured thereto are wheels h, having'cam-hubs 7L2, similar to i thecam-hubs d, on the ends of the printingcylinder, and the cam-hubs 7L2are provided with cam projections 7L similar to the cam projections (iand which also operate in connection with the heads yr of the arms g.The wheelsh are also preferably provided with annular raised portions7%, having recesses 72/ in which are pivoted pawls h, similar to thepawls d, and the pawls h operate in connection with the outer fingers gon the end members e of the supplemental printing-frame, while the pawlsd operate in connection with the inner fingers g of the end members ofthe supplemental printing-frame, and the wheels hare also preferablyprovided at a predetermined point on their outer edges with camprojections k Wound on the opposite ends of the rod or shaft 0 on whichthe supplemental printing-frame e is mounted, are springs 71, and oneend of these springs is secured to the supplemental printing-frame andthe other to the main printing-frame, and said springs normally serve tohold the supplemental printing-frame in its raised position or out ofcontact with the printing-cylmder.

The arm I) on the shaft 5 need not necessarily be employed in all cases,but is preferably employed in large machines in order that an operatormay conveniently manipulate the device, and in practice a roll of paper(partially shown at L) is mounted in the main frame, and whenever it isdesired to tear off a strip or sheet thereof in the usual manner and itis desired to print an advertisement on said strip or sheet and theinkingroller e having been previously inked the 'main printing-frame isdepressed by pulling forwardly and downwardly on the arm 11 if said armbe employed. This operation forces the supplemental printing-frame edownwardly, so that the inking pad or cushionthereon will come incontact with the v type-plate d on the printing-cylinder d, and

at the same time the printing-cylinder is forced downwardly onto theroll of paper, and when the parts are in this position a strip or sheetof the paper may be pulled out or off of the roll and torn off in theusual manner, and the desired advertisement will be printed thereon. Ifthe arm 12 is not employed, the supplemental printing-frame may bedepressed by means of a handle i connected therewith, by pressingdownwardly and backwardly on said handle, and 7 this will result indepressing the supplemental printing-frame e, as hereinbefore described,and also in depressing the main printing-frame so that theprinting-cylinder d will come in contact with the paper-roll i. In theoperation of depressing or turning the supplemental printing-frame 6above described the dogs f are released from the ratchets 5 as shown inFig. 4, which enables the main frame to be depressed, and as soon as thepressure on the handle 17 of the supple-- I mental printing-frame isreleased the springs f force the dogs f back into engagement with theratchet b. The dogs f and rod f ,0011;

nected therewith, are adapted to be employed where the main frame is ofsufficient weight to operate by gravity, and in the rotation of thewheels 7L2 after the printing has been accomplished the projections 71/7thereon would force the main frame upwardly, and the dogs f being movedupwardly on the segmental ratchet b will hold the main frame in theraised position, and the type would be removed from the paper, as willbe understood.

The arrangement shown in the drawings of the arms 9 and pawls d isutilized to increase the space between two impressions of the typewhenever it is desired to print continuously on a strip of paper drawnfrom the roll '5, and the operation of these parts is as follows:Supposing the pawls d and h be in the positions shown in Figs. 4 and 5and a strip of paper to be drawn from the roll i, the withdrawal of thesaid strip would rotate the wheels (1 of the printing-cylinder d, butwould not rotate the wheels h, for the reason that the pawls h thereonwere in engagement with the fingers g of the arms g; but when the wheelsd are so rotated the cam d thereof, which is preferably mounted thereonslightly in advance of the pawls d, coming into contact with the heads gwould force the supplemental frame 6 backwardly and upwardly, therebyreleasing the pawls h from the corresponding fingers g and the wheels hmay then be rotated in the withdrawal of the sheet of paper. After thepawls h have been released, as just described, the arms 9 are againforced inwardly to the concentric surface of the cam-hubs d and thepawls d on the wheels d are engaged by the corresponding fingers g andthe printing-cylinder cl is thereby held against rota-V tion. When thewheels h have been rotated approximately through their full rotation,the cams 7L3 thereon force the arms 9 outwardly, as previouslydescribed, thereby releasing the pawls ci 'from the correspondingfingers g by which they were engaged, and the rotation of theprinting-cylinder d is again made possible; but at approximately thissame time the pawls h are again engaged by the corresponding fingers gand the wheels h are locked against rotation. Assuming that in the firstrotation-of the printing-cylinder an impression had been made by thetype thereof upon the paper being withdrawn, if the cylinder d werepermitted to continue its rotation another impression would be made, thebeginning of which would be a distance equal to the circumference of thewheels (1 but by means of my arrange ment the wheels d being lockedagainst rotation until the wheels h have accomplished a full rotation,the distance between the beginning of the impressions is therebydoubled, or nearly so, according to the relative positionsof the pawlsdand h, and this locking and releasing of the printing-cylinder and thewheels it occur alternately, as will be understood, and if the wheels hbe rotated backwardly manually, thereby changing the relative positionsof the pawls (Z and h the distance between the impression is lessened,as will be seen. When suflicient paper has been drawn from the roll 'i,releasing the pressure on the arm b or handle i will when the springs care employed permit the main frame 0 to rise and no printing isaccomplished, even though more paper be drawn out, or if the springs cbe not employed the frame 0 is raised by means of the projections IL7 onthe wheels h, and the said frame is held in its raised position by meansof the dogs f.

In Figs. 7, 8, and 9 of thedrawings I have shown a modification of theconstruction heretofore described, said modification being made topermit of printing in two colors, and in this form of construction Iprovide the main printing-frame c and spring therefor, as well as theprinting-cylinder d, with the parts heretofore descrbied, and inaddition with supplemental wheels 7c and k and the inking-frame e isalso employed, as well as the inking-roller e therein; but theinkingroller is adapted to move outwardly against the pressure of aspring W, as clearly'shown in Figs. 7 and 8, and is provided with awheel k at each end thereof, which wheels are adapted to rotate upon thewheels k of the prin ting-cylinder d.

As shown in Fig. 7 of the drawings, the inking-cylinder e is providedwith a segmentgear m, engaging a similar segment-gear m on asupplemental inking-frame m which is pivotally mounted, as shown at m.to the main frame 0, and the supplemental inkingframe m is providedwith an inking-roller m I which is adapted to be moved outwardly againstthe action of a spring m", as clearly shown in Figs. 7 and 9 of thedrawings, and the inking-roller m is also provided with a wheel m ateach end thereof, and said wheels m are adapted to rotate on the wheels7c of the printingcylinder.

As clearly shown in Figs. 7 and 9, the wheels 7c and k are provided atintervals with recesses n and of, into which the corresponding wheels mand k are adapted to enter, this operation being made possible by meansof the springs k and 7c, and when the wheels of one of theinking-rollers enters the corresponding recesses the said inking-rolleris forced inwardly into contact with the type-face, said type, however,not being shown in Fig. 7, although clearly shown in Fig. 9, and in thismanner the inking of a line of type is performed with an ink of onecolor by means of the one inking-roller and another line of type maybeinked another color by means of the other inking-roller, the recesses inthe wheels 75 and being arranged therein in order to accomplish thisresult. In the operation of this form of my invention the inking-frame cis forced downwardly manually, and this operation serves to force thesupplemental inking-frame m downwardly, at the same time forcing themain frame 0 downwardly until the wheels (Z rest on the roll of paper,and when a strip of paper is withdrawn from said roll theprinting-cylinder (1 is rotated, as previously described, and the inkingof the type in the different colors results and the imprint is made onthe paper in the manner hereinbefore described. Although I have shownthis form of my invention adapted to be manually operated, it will beunderstood that the same may be operated in a manner similar to thatshown in Fig. 8 of the drawings by means of the arm 6 the method offorcing the printing-frame downwardly not being the basis of thisinvention, and any other suitable method of producing this result may beemployed. It will therefore be seen that my invention is adapted toprint on a roll of paper at predetermined intervals, this printing beingaccomplished during the withdrawal of a strip of paper from said roll,and said printing is accomplished in both my forms of constructionwithout the blurring due to the type-face being drawn along the paperbeing printed upon, and while I have shown specific looking devices ordevices for intermittently permitting printing it will be ovbious thatthese may be modified materially without departing from the spirit of myinvention or sacrificing its advantages, and with this reservation hat Iclaim as new, and desire to secure by Letters Patent, is
